Community Software – a part of PrimeKey Open Source As part of our Open Source policy we offer our software in free community editions. This means that you can download EJBCA Community and SignServer Community from SourceForge, both under LGPL licence. Read more about LGPL here. The two Community editions are of course developed with the consistent high quality focus of PrimeKey, but are limited to the core functionality. They are great tools for those who want to learn and use basic PKI, without any need for advanced functionality or certifications.
